## Detailed Description

This file implements the server-side part of the DMX protocol. A vector of fucntions is provided at extension initialization time, so most all of the useful functions in this file are declared static and do not appear in the doxygen documentation.

Much of the low-level work is done by functions in dmxextension.c

Please see the Client-to-Server DMX Extension to the X Protocol document for details about the protocol.
